P2000 - OBD Trouble Code
OBD Code P2000 - NOx Adsorber Efficiency Below Threshold Bank 1
The trouble code P2000 can be defined as NOx
Adsorber Efficiency Below Threshold Bank 1. It is a general OBD2 diagnostic
trouble code which would indicate a malfunction with the NOx Trap;
specifically, the NOx trap has efficiency that is below threshold for Bank 1.
The engine control module inspects the levels of NOx and if it would detect a
very low threshold, then the P2000 error code would start flashing. It would
also give rise to the illumination of the check engine light.

It is always good to learn more! That is the reason why we are here to help you out in gaining more knowledge about the P2000 error code. The levels of NOx are being monitored by the engine control module. This trouble code would be set by the ECM when the levels of NOx would not be as per the specifications set by the manufacturer. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.
What causes this problem with the NOx Adsorber Efficiency Below Threshold Bank 1?
- Some flaws in the NOx trap or NOx
trap element
- Malfunctioning diesel exhaust fluid
injection system
- The NOx reductant fluid might not
be adequate enough
- Untreatable exhaust gas
recirculation system
- Leakage exhaust upstream of the NOx
trap
Replace/Repair These Parts To Fix Code P2000
- Engine Control
Module - There can be some engine performance
issues due to faulty engine control module. If the ECM fails or has any
problems it can lead to performance issues with the vehicle like misfires,
hesitation, loss of power, and sometimes even decreased fuel economy.
- Exhaust
Gas Recirculation Valve - Did you just see
check engine light flashing on your dashboard? If the computer would detect
some fault with the automobile’s EGR valve circuit, then it would set up the
check engine light so that the driver is notified about the fault. Don’t waste time and
get them replaced or else this fault code can turn up.
- Diesel Exhaust
Fluid Pump - The diesel exhaust fluid pump needs to work properly if the
transmission system has to perform. If it is not functioning, the transmission
may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new
one from us!
- Powertrain Control
Module - PCM stands for powertrain control
module. It is a car part, a control unit which is utilized on motor vehicles.
It is generally a combined control unit, consisting of the engine control unit
(ECU) and the transmission control unit (TCU).
- Electronic Control
Unit - If your automobile's check engine light remains on constantly, and
never goes off, there's a good chance that your vehicle has a damaged
electronic control unit. There are a lot of reasons why a car's check engine
light will remain on. The most common reason is a defective ECU.
- Diagnostic Tools - It is always advisable to use correct tools and
equipment while resolving any OBD code issue as even small mistakes can lead to
wrong diagnosis. Thus, always take help from a professional who has the
knowledge and experience to such tools in efficient manner. Buy new quality
diagnostic tools from us today!

Easy Diagnosis Of Engine Error OBD Code P2000
Here are some steps which you should follow in order to diagnose this fault code:
- This is a general type of error code which is diagnosed with the help of a scanner.
- The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
- If he happens to find any additional error codes, he has to address them as well.
- Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
- If the error code does not return, then there can be an erratic condition.
- Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
- Check for the damaged catalytic converter for error.
- Then the scan tool would be utilized for proper sensor and solenoid operation.
- If all the components seems to work perfectly, inspect the ECM for faults and replacement along with reprogramming.
Common Mistakes When Diagnosing The P2000 Code
- Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully.
- The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
